I just got GTA 4, and was in awe with the scope of the game. But there is a problem: the game freezes every 2 seconds, give or take, no matter the configuration I choose. I've got the feeling that it's not the Video Card, but rather the processor that is the choke point, as the cut scenes look fluent and with good framerate, even the benchmark.
Has anyone else noted this? Is there some configuration I can tweak to lower the processor stress?
My computer is a Athlon X2 3600+ EE (2GHz), 4GB RAM 666MHz, M4N78 SE Motherboard and a PNY GeForce 9600 GT video card.
